The difference in price paid by an urgent buyer and received by an urgent seller is the liquidity cost. Since brokerage commissions do not vary with the time taken to complete a transaction, differences in bid–ask spread indicate differences in the liquidity cost.
283:. The effective spread is more difficult to measure than the quoted spread, since one needs to match trades with quotes and account for reporting delays (at least pre-electronic trading). Moreover, this definition embeds the assumption that trades above the midpoint are buys and trades below the midpoint are sales.
436:, while other metals may have wider bid-ask spreads due to lower trading volumes, less liquidity, or large fluctuations in supply and demand. For example, rare metals like platinum, palladium, and rhodium have lower trading volumes compared to gold or silver, which can result in larger bid-ask spreads.

If the USD/JPY currency pair is currently trading at 101.89/101.92, that is another way of saying that the bid for the USD/JPY is 101.89 and the offer is 101.92. This means that currently, holders of USD can sell US$ 1 for 101.89 JPY and investors who wish to buy dollars can do so at a cost of

Quoted and effective spreads represent costs incurred by traders. This cost includes both a cost of asymmetric information, that is, a loss to traders that are more informed, as well as a cost of immediacy, that is, a cost for having a trade being executed by an intermediary. The realized spread

The simplest type of bid-ask spread is the quoted spread. This spread is taken directly from quotes, that is, posted prices. Using quotes, this spread is the difference between the lowest asking price (the lowest price at which someone will sell) and the highest bid price (the highest price at
207:
Quoted spreads often over-state the spreads finally paid by traders, due to "price improvement", that is, a dealer offering a better price than the quotes, also known as "trading inside the spread". Effective spreads account for this issue by using trade prices, and are typically defined as:
111:. For a round trip (a purchase and sale together) the liquidity demander pays the spread and the liquidity supplier earns the spread. All limit orders outstanding at a given time (i.e. limit orders that have not been executed) are together called the Limit Order Book. In some markets such as

where the subscript k represents the kth trade. The intuition for why this spread measures the cost of immediacy is that, after each trade, the dealer adjusts quotes to reflect the information in the trade (and inventory effects).

If the current bid price for the EUR/USD currency pair is 1.5760 and the current offer price is 1.5763, this means that currently you can sell the EUR/USD at 1.5760 and buy at 1.5763. The difference between those prices (3
